I've been advised in the past about running custom grind camshafts with stock valve springs and I've been debating changing them
However... What should I know before I buy them
AND
How would I install them? are there any special tools I need? Do I need to retune?

You should upgrade your valvesprings for any non-stock cam. Supertech 78lb kit has a pretty good tolerence for coil bind (i forget the actual spec). There's a specific tool for our springs, a traditional valvespring compressed is too wide to reach the base of our springs.

Very well said! Secondly a retune usually isn't necessary, but you may notice a slight change if you're running a high lift/duration cam on stock springs, you most likely may be having valve float issues... It's a must to upgrade springs if you're running any non stock cam and or greater then 10 psi seeing as how myself and skunk found out our stock springs cant handle a lot of cylinder pressure when boost is applied...

I see them on eBay occasionally, and I know for sure Snap On makes one. The one we need is two "U" brackets that bolt to the top of the head, two rods that slide through the brackets, then the compressor uses the rods to push against and put tension on the valve spring. Pretty convenient tool, takes about 10 minutes to take everything out.
